Most local codes allow one roof-over of existing shingles, although it may void the warranty of the new shingles.
Doing it is cheaper than removing the old shingles first, but the new shingles usually don't last quite as long.
Your call.
Good Luck!

If you search the archives you'll find several extensive discussions on the topic. Depends on building codes in your area, condition of existing roof, etc.
